摘　　要：可调螺距螺旋桨(调距桨)桨毂机构及桨叶等在运行中会承受较大的载荷,利用加载重块旋转产生的离心力模拟调距桨在叶根法兰中心处推力弯矩、扭力弯矩、离心力和离心力扭矩,使得试验能高效简易地实现.通过单质点等效块体旋转,将模型大大简化,在此基础上分析定螺距和调距两种状态下设计算法.分析结果为桨毂强度测试试验奠定了基础.The controllable-pitch propeller（CPP）hub and blades are under relative high loads in the process. In order to find an efficient and simple way to conduct an experiment, the loading equipment is used to simulate the thrust moment, wrest moment, centrifugal force and centrifugal moment on the center point of flange. The model is simplified by substituting particle for block. Then the fixed pitch status and adjusting pitch status are analyzed. These analysis results provide essential foundations to the strength experiments of propeller hub.
